You need to be more specific about what you mean by Rohloff-specific
hardware. To use a Rohloff hub a frame needs these features:
1. A way to fit a 135 mm wide hub
2. Appropriate chain line (not really a feature of the frame as this is
adjusted with the bottom bracket / crankset combination)
3. A way to adjust the chain tension which can be:
a. spring chain tensioner like on a derailluer bike, Rohloff supplies
one that attaches to a standard derailluer hanger
b. eccentric bottom bracket
c. sliding rear dropouts
d. horizontal dropouts like a track bike but this setup works best with
nutted axles and perhaps not at all with a quick release skewer.
4. A way to counteract the torque produced by the hub which can be:
a. Rohloff specific dropouts
b. A clamp-on torque arm from Rohloff that will fit most bikes
c. A "dog-bone" attachment from Rohloff that bolts on to a disk brake
mounting boss on the frame
You can take almost any frame that will fit a 135 mm rear hub and use a
Rohloff chain tensioner and Rohloff torque arm and use a Rohloff hub. If
you want Rohloff specific sliding rear dropouts (so you won't need a chain
tensioner or torque arm or dog-bone attachment to disk brake mounts), I
don't think you will find this in a "production" frame anywhere, especially
in the U.S.A. It is readily available from many USA or other custom frame
builders. Bob Jackson cycles in Leeds, UK made my touring bike frame like
this for roughly the same price as a Rohloff hub.
